ascx控件不觸發JavaScript的

Question

我的.ascx低於件

function confirmationDelete() 
    {  
     var r = confirm("Are you sure you want to delete this target"); 
     if (r == true) { 
      return true; 
     } else { 
      return false; 
     } 
    } 


<asp:Button ID="btnDeleteTarget" runat="server" Text="Delete Target" CssClass="btnDeleteTargetClass" ValidationGroup="validateformgroup" CausesValidation="true" OnClick="btnDeleteTarget_Click" Visible="False" /> 

ascx.cs低於線

btnDeleteTarget.OnClientClick = "return confirmationDelete()"; 

我仍然沒有得到確認提示。頁面只是刷新。我究竟做錯了什麼？

嘗試在開發人員工具欄中放置斷點，但它不調用我的JS函數。

Answer 1

試試這個代碼

在你*的.ascx：

<asp:Button ID="btnDeleteTarget" runat="server" Text="Delete Target" CssClass="btnDeleteTargetClass" ValidationGroup="validateformgroup" CausesValidation="true" OnClick="btnDeleteTarget_Click" Visible="False" /> 

在的.cs C＃：

protected void Page_Load(object sender, System.EventArgs e) 
{ 
    if (!IsPostBack) 
    { 
     btnDeleteTarget.Attributes["Onclick"] = "return confirm('Do you want Delete ?')";   
    } 
} 

protected void btnDeleteTarget_Click(object sender, EventArgs e) 
{ 
    Page.Validate(); 
    if (Page.IsValid) 
    { 
     //Delete all 
    } 
} 

Answer 2

使用此您的按鈕中的OnClientClick屬性：

OnClientClick="return confirm('Are you sure you want to delete?');" 

這將是你的代碼：

<asp:Button ID="btnDeleteTarget" runat="server" Text="Delete Target" CssClass="btnDeleteTargetClass" ValidationGroup="validateformgroup" CausesValidation="true" OnClientClick="return confirm('Are you sure you want to delete?');" Visible="False" />
